Given recent breakage, has the patchset been run through any tests on older kernels that do not support sample_id_all? e.g., 2.6.34 (WRL4). What about tests with the other perf commands -- script to dump events, trace on a file with with multiple processes -- to verify no impact on comm output, especially multithreaded processes with named threads. I can certainly do those tests in time, but can't guarantee a timeframe and want to make sure it gets done before merging.
Thanks, David
